对太阳黑子精细结构的高分辨率观测是什么导致了半影的丝状结构，磁场形成了一个互锁的梳状结构，围绕着太阳黑子的黑暗中央本影？这种意想不到的几何形状只能通过理解磁场与点外小规模湍流对流之间的相互作用来解释。这种相互作用导致磁通量向下传输，将磁通量管淹没在太阳表面以下，并形成强烈的凹槽结构。该过程的理想化版本可以通过数值实验来演示。抽象的
High-resolution observations of fine structure in sunspots a very what causes the filamentary structure of the penumbra, with magnetic fields forming an interlocking comb-like configuration, that surrounds the dark central umbra of a sunspot? This unexpected geometry can only be explained by an understanding of the interaction between magnetic fields and small-scale turbulent convection outside the spot. This interaction leads to downwards transport of magnetic flux, submerging magnetic flux tubes below the solar surface and resulting in a strongly fluted structure. An idealized version of this process can be demonstrated in numerical experiments. Abstract
